Abstract

There has been significant research interest over recent years in the use of public digital displays and their capabilities to offer both interactivity and personalized content. A promising approach in interacting with large public displays has been the use of ubiquitous cell. A dual screen approach suggests a number of intriguing possibilities including a potential solution to the problem of managing conflicts when using a shared screen in a public setting. We believe, we can build on top of Norman’s seven stage model of interaction, and that such a formalism would help designers better cope with the requirements of a dual display design.
